Probably the most anticipated battle that never happened in LUK SIU FUNG, Book 1 (THE GOLDEN ROC KINGDOM'S TREASURE), other than that *other* most anticipated battle that also never happened (i.e. Luk Siu Fung vs. Sai Mun Chui Sheut), was Luk Siu Fung vs. Fok Teen Ching (Chief of the Sky Lyre Union). Until just before the end of the novel, Luk Siu Fung (and probably many readers) believed that Fok Teen Ching was the real culprit behind the Green Shirts Pavilion. Many were expecting a violent showdown between Luk and Fok. There were two opportunities for them to fight: the first was aborted by Luk Siu Fung himself, who did not want to offend his good friend San Sai Ngan (Hero of Kwan Tsung), the apprentice nephew of Fok Teen Ching. The second fight was also aborted because Fok Teen Ching was murdered by the *real* culprit of Book 1: Fok Yau.
But how would the fight have gone down? Luk Siu Fung probably would have ultimately won because 1). he's the main character and 2). he would have outwitted and outmaneuvered Fok Teen Ching. But could Luk Siu Fung hoped to have matched Fok Teen Ching in a straight martial arts battle? Luk Siu Fung estimated that Ngor Mei Sect's Leader, Dook Goo 1 Hok, could have killed him (Luk) with his Sabre-Sword Combination Onslaught; Luk Siu Fung also worried about Sai Mun Chui Sheut because he very much doubted that Sai Mun Chui Sheut could defeat Dook Goo 1 Hok. As it was, Sai Mun Chui Sheut barely edged out Dook Goo 1 Hok because DG had just had his inner power drained by Fok Teen Ching. Dook Goo 1 Hok had been so powerful that Luk Siu Fung thought that neither he nor Sai Mun Chui Sheut could have overcome him, but Fok Teen Ching seemed to very casually drain away all of Dook Goo 1 Hok's inner power, leaving him vulnerable to being killed by Sai Mun Chui Sheut. That suggests that Fok Teen Ching's martial arts were at a higher level than Luk Siu Fung's.
